There are thousands of resources on lie-detection. Nothing seems to agree with the other, and it's difficult to sift through the BS to find the factual information. Using the Behavioral Table of Elements and about 6,000 research documents and 120 years of research, this pocket-sized guide should be handy enough to get you well on your way to seeing the truth.

ADVANCED QUESTIONING TECHNIQUES

Do not phrase your questions in the form of a direct accusation. Instead of asking directly if someone cheated, ask if anything interesting happened last night.

If a question sounds rehearsed, ask them about the events out of order or backwards. They likely didn't rehearse it that way.

After someone denies a question about wrongdoing, ask them what should happen to the person that DID do it.

If you ask a question directly, do it by surprise and look for hesitancy.

Followup with denials with the word, 'Really?'

Ask questions with bait in them: "Is there any reason someone would have said they saw you there last night?"

Set the Scene: Use a serious or playful tone in order to enhance their anxiety or create more comfort as needed.

Make deliberate speech errors and display sloppy movements in order to lower suspect's defenses

Don't ask questions you don't want the answer.

Make an accusation far worse than their offense and cause them to lower the bar and admit to the 'smaller' offense

Visual Signs of Deception

Limited Physical Expression: Movements and body language (especially in the upper body) will be minimized to a lesser extent than the person's norm due to more effort being cognitively expended.

Hand-to-Face Gestures: Anytime during an answer to a question the hands touch the face or mouth.
